Its in the patchnotes for patch 5 that they allegedly unblocked the alurlssrin scene. I've also seen a youtube video from like a month ago, post patch 5, where someone had that conversation, their Tav was not a drow though. I'm not sure if its modded or not, since any video of that scene from before patch 5 was modded, as far as I know.
I just don't know if it's simply still bugged despite their patchnotes claiming otherwise, or it's really just insanely specific. There is some scenes and lines with other characters that you can get, but it's rather specific about what you need to do (or not do) to get them. Like with Isobel
when she speaks about Aylin taking a month-long walk
